Both Olympus XZ-2 iHS and Canon S100 have 1/1.7-inch sized 12.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the XZ-2 iHS and S100 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus XZ-2 iHS and Canon S100 Cameras
Olympus XZ-2 iHS and Canon S100 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Olympus XZ-2 iHS and Canon S100 sensors have been tested by DxO and the results show that S100 has a better overall score of 50, 1 points higher compared to XZ-2 iHS's score of 49.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Olympus XZ-2 iHS
or the
Canon S100 ,
including hyperfocal distance.
